Reset Timer ICsHow to use
PC or electrical equipment usually have the function of reset/reboot/initialize by pressing a reset button or power button or two different buttons at the same time for over a certain period of time. In order to achieve this function, reset timer ICs are used which can count the time of the buttons being pressed.
Ricoh reset timer ICs, R3200 series and R3201 series can output a reset signal when it detects the two input buttons being pressed continuously and simultaneously for a certain period of time. These reset timer ICs enable constructing a smaller and lower-supply-current reset with timer function compared with discreet circuits' solution.
As for R3200 series and R3201 series, by making one of the inputs of the reset timer IC tied to GND, the reset timer function with single input button can be realized.
